Parents need to know that this famous sitcom, which has become a permanent part of the pop culture lexicon, purposely portrays characters who are selfish, amoral, and not always likeable. Lying, cheating, and gossiping are frequent plot elements. Episodes often center on characters' dating dilemmas and include discussions of contraception, masturbation (though the word is never uttered), and personal habits. Teens and parents who enjoy smart humor will find much to celebrate in this series, though younger viewers may be bored or confused by the adult dynamics.
